Carbon and nitrogen cycling in tundra soils - Daring Lake

Knowledge of the ability of the soil to mineralize nitrogen (N) and release greenhouse gases (GHG) at the landscape scale is critical to predict and model future effects of climate change on Arctic soil organic matter (SOM). The objective was to examine how SOM characteristics influences soil gross nitrogen mineralization and soil carbon dynamics in several Arctic ecosystems.了解土壤在景观尺度上的氮（N）矿化能力与温室气体（GHG）释放能力，对于预测和模拟气候变化对北极土壤有机质（SOM）的未来影响至关重要。本研究旨在探究北极多个生态系统中，土壤有机质特征如何影响土壤总氮矿化过程与土壤碳动态。
